Labdhi Metals is a reputed manufacturer, stockist, and exporter of high-performance SMO 254 Fittings, engineered to serve critical industries that require superior corrosion resistance and strength. SMO 254, also known by its material designation UNS S31254, is a super austenitic stainless steel developed to resist the harshest environments, particularly those with high chloride content such as offshore platforms, chemical processing units, pulp & paper facilities, and desalination plants. Labdhi Metals ensures that each fitting adheres to strict industry standards to deliver long-lasting performance even under extreme operational conditions.
SMO 254 is known for its high levels of molybdenum, nickel, and nitrogen, which give it exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. These properties make SMO 254 fittings a preferred choice for highly corrosive environments where conventional stainless steels like 316L or Duplex grades may fail. Labdhi Metals manufactures a wide range of SMO 254 fittings including elbows, tees, reducers, stub ends, and caps in both seamless and welded forms, ensuring compatibility with a variety of industrial piping systems.
As a trusted stockist, Labdhi Metals maintains a ready inventory of SMO 254 fittings in sizes ranging from ½” NB to 24” NB, and in pressure classes ranging from 150# to 2500#. These fittings are available in different types including butt-weld, socket weld, and threaded end connections. Each product is precision-engineered and undergoes stringent quality control procedures, including dimensional inspection, ultrasonic testing, and PMI (Positive Material Identification) to ensure flawless performance.
Labdhi Metals is also a leading exporter, supplying SMO 254 pipe fittings to customers across Europe, the Middle East, Africa, North America, and Asia-Pacific. All products comply with international standards such as ASTM A403, ASME B16.9, B16.11, and MSS-SP 43. Each shipment is accompanied by comprehensive documentation, including material test certificates (MTCs) as per EN 10204 3.1/3.2, ensuring full traceability and compliance with global project requirements.
